What is a picometer used to measure?

A picometer measures extremely small distances on the atomic and sub-nanometre scale, such as atomic bond lengths and interatomic spacings.

What scale does an exameter represent?

An exameter equals one quintillion meters (10^18 meters) and is used to describe immense distances in astrophysics and cosmology.

Why convert from picometers to exameters?

This conversion helps bridge understanding between tiny atomic-scale distances and vast cosmic scales, useful in multidisciplinary scientific contexts.
